Description

Adds mob collision damage based on size differences.

Update:

Players are now given a random size on first spawn.
Optional toggle to turn on and off both the collision logic and random size. Both are on by default.
Can coustomize each randomly picked size in config file.

I've only tested it on 1.20.1 with pehkui 3.8.2, but it should work on other versions.

How the collision logic works:

Spoiler

First it checks if the bigger mob is moving into the smaller mob.
Then it finds the scale difference between the two coliding mobs.
Then it checks if the bigger one is at least 4x the scale.
Then it checks if the bigger mob is less than 100x the scale.
Then it adds random variance to the difference.
After adding varience it checks if the bigger mob was either walking, sprinting, crouching, or falling, adding different multipliers off that.
Finally it checks if config allows the smaller mob to die before applying the difference as damage to the smaller mob.
